An enchantment is a permanent effect added to one card in your deck. A card holds one enchantment at a time, and a card that already has one cannot take another. Upgrading the card keeps the enchantment.

Cards that can never be enchanted

Status, Curse and Quest cards cannot be enchanted, and neither can an Unplayable card in your deck.

Clone at rest sites

Pael's Growth enchants one card with Clone and adds a Clone option to every rest site. Choosing it adds a copy of every Clone card in your deck, and each copy keeps Clone. One Clone card becomes 2 after the first use, 4 after the second and 8 after the third. The Clone option replaces resting or upgrading at that rest site.

Enchantments and upgrades

Enchantment numbers belong to the enchantment, not the card: upgrading a Sharp card does not change Sharp's bonus. See how the two economies of a run work for the other ways a deck gets stronger.
